Best answer: Is phenol or alcohol more soluble?

Solubility. Alcohols : Alcohols are soluble in water because they form intermolecular hydrogen bonding with water molecules. … However, the solubility of phenols is much lower than that of alcohols due to the presence of the larger hydrocarbon part (benzene ring).

Why alcohols are more soluble than phenol?

Alcohols undergo intermolecular H-bonding while hydrocarbons do not. Hence, they are more soluble in water than the hydrocarbons of comparable molecular masses. The nitro-group is an electron-withdrawing group. The presence of this group in the ortho position decreases the electron density in the O-H bond.

Is phenol more soluble in water?

Water is a polar solvent. Hence polar substances like salts are more soluble in it. Phenoxide ion is more polar than phenol itself. Hence is more soluble in water.

Which is more soluble in water phenol or methanol?

Larger the hydrocarbon part in the molecule lesser is the solubility. Since in methanol only -CH3 group is attached to -OH it is easily soluble but in case of phenol due to the larger hydrocarbon part (benzene ring) in the molecule which decreases its solubility.

What are the differences in solubility between alcohols and phenols?

The comparatively large aromatic ring limits their solubility in water, but phenols exhibit better solubility than the corresponding alcohols. In phenols, the hydrogen bonding is strengthened by the higher polarity of an oxygen–hydrogen bond dipole connected to an electron-withdrawing aromatic ring.

Is phenol soluble?

Phenols are similar to alcohols but form stronger hydrogen bonds. Thus, they are more soluble in water than are alcohols and have higher boiling points.

Is phenol soluble in ethanol?

All Answers (5) I would expect phenol to be considerably more soluble in ethanol than in water. The alkyl groups of ethanol will help to solubilize the non-polar aromatic ring of phenol. … BTW solubility always increases with temperature, regardless of solvent.

Is phenol more soluble in water than alcohol?

Phenols : Phenols also form hydrogen bonds with water and hence are soluble in water. However, the solubility of phenols is much lower than that of alcohols due to the presence of the larger hydrocarbon part (benzene ring).

How is phenol different from alcohol?

Phenol reacts with neutral ferric chloride solution to give violet colouration whereas alcohols do not react.

Why is phenol water soluble?

Phenol is somewhat soluble in water because of its ability to form hydrogen bonds with the water.

Why alcohols are soluble in water?

Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water.

Why phenol is less soluble in water than ethanol?

Phenol is partially soluble in water because it has an ability to form hydrogen bonding with water molecules. However phenol is less soluble than alcohols because of the presence of a large hydrophobic benzene ring. This benzene ring being water repelling causes hindrance during the solubility of phenol in water.

What is the solubility of ethanol?

Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount.

Alcohol solubility chart.

Name Formula Solubility
Methanol CH3OH miscible
Ethanol C2H5OH miscible
Propanol C3H7OH miscible
Butanol C4H9OH 0.11

Is phenol more soluble than ethanol?

Phenol is sparingly soluble in it is non polar in nature. Thus ethanol is more soluble in water compared to phenol.

Why does higher alcohol decrease solubility?

Higher alcohols have large no. of hydrocarbon chains which results in more steric hindrance to make bonds which result in less solubility.

Is phenol A solvent?

Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile.
